As demonstrators were clashing with police in Paris and protests were being held across France on Saturday, Mr Trump said: "The Paris Agreement isn’t working out so well for Paris. Protests and riots all over France. People do not want to pay large sums of money, much to third world countries (that are questionably run), in order to maybe protect the environment. Chanting 'We Want Trump!' Love France."

Sunday Telegraph reporters, placed across the city, heard no such chants.

He later tweeted that the protests were "very sad" and reiterated his call for Mr Macron to pull out of the Paris climate change deal, and agree to lower taxes.

He did not specify how he believed the agreement and taxes were linked.

Very sad day & night in Paris. Maybe it’s time to end the ridiculous and extremely expensive Paris Agreement and return money back to the people in the form of lower taxes? The U.S. was way ahead of the curve on that and the only major country where emissions went down last year!
